Lower glume apex acute, or acuminate. Upper glume lanceolate; 4–5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute, or acuminate; muticous.

FLORETS Fertile lemma oblong; 4–5 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acute, or acuminate; muticous. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
